To succeed in this topic, you need to:
Be familiar with oxygen and sulphur as members of Group 16 (previously Group 6) of the Periodic Table.
Be familiar with physical and chemical trends in the Periodic Table, and that p-block elements may have metallic or non-metallic properties.
Be familiar with elements in the same Group having similar chemical properties, due to their electron configurations and number of valence electrons available.

After working through this Chemistry Factsheet, you will:

Be aware of the increasing trend in metallic characteristics, and decreases in electronegativity, in Group 16 elements, descending the group.
Be aware of similarities in the variable oxidation states, leading to similar chemical reactions, for Group 16 elements.
Be able to describe Group 16 oxides and their acidic properties
Be able to describe the trend in Group 16 hydride’s boiling-points, explaining the anomalous behaviour of water (oxygen hydride).
